Examine the diagram. What are the measures of angle 1 and angle 2?

Dmitry_Shevchenko [17]

The measure of angle one is equal to 60.75 degrees because angle 1 and 60.75 angle are corresponding, so they are congruent.

The measure of angle two is 119.25 degrees because it is supplementary to angle 1.

Hope this helps! :)

Find a vector function that represents the curve of intersection of the paraboloid z=3x2+2y2 and the cylinder y=6x2. Use the var

Cerrena [4.2K]

Answer:

$\vec{r(t)}=t\hat{i}+6t^2\hat{j}+(3t^2+72t^4)\hat{k} \text{ For }t \in (-\infty, \infty)$

Step-by-step explanation:

First plug the equation of y into the equation of z, so that we get their intersection:

We plug

$y=6x^2$

Into: $z=3x^2+2y^2$

So, we get:

$z=3x^2+2(6x^2)^2\\z=3x^2+2(36x^4)\\z=3x^2+72x^4$

Then we set

$x=t$

And plug that in the equation $y=6x^2$ and the one we just got for z.

So that we get:

$y=6t^2, z=3t^2+72t^4$

Therefore, the vector function that represents the curve of intersection is:

$\vec{r(t)}=t\hat{i}+6t^2\hat{j}+(3t^2+72t^4)\hat{k} \text{ For }t \in (-\infty, \infty)$

Savatey [412]

Answer:

a. 2.3 sec and 5 sec

Step-by-step explanation:

The graph is symmetrical about the time (t) that makes d=0. That makes the line of symmetry be ...

110/30 = t ≈ 3.67

This will be the average of the two times, so their sum is ...

t1 +t2 = 2×3.67 = 7.3

Only one answer choice has a sum of 7.3 seconds:

2.3 sec and 5 sec
